ACS has recently added new amplifier synthesis software to its line of circuit synthesis products. The wizard-like GUI quickly and effortlessly guides the user through the process of entering the specifications for the automatic synthesis of a wide variety of amplifier circuits, including single or multistage amplifiers, balanced amplifiers, differential (push-pull) amplifiers and low noise amplifiers. The LINC2 Pro RF and microwave circuit design and analysis software combines circuit synthesis, simulation, optimization and statistical yield analysis into a single integrated design environment.

The model SW1006 is the latest version of the company’s radiated susceptibility, conducted immunity and pre-compliance emissions software. Model SW1006 automatically performs both calibration and immunity testing in full compliance with IEC 61000-4-3, 4-6, MIL-STD 461/462 RS103, CS114, RTCA/DO160 Section 20 specifications. The software also supplies the user with selectable test parameters and a “thresholding” mode for pre-compliance investigation of equipment susceptibility, as well as closed loop leveling. Pre-compliance emission testing can be done with the use of a spectrum analyzer and either a pre-amp or LISN. The SW1006 software is designed for use with the supplied NI PCI-GPIB interface card for instrument communication.

The CAVITY™ software packages for Microsoft Windows and Macintosh OS X are versatile programs that perform all of the instrument control, calibration and data processing for measuring complex permittivity and permeability using a wide variety of resonators. The software supports thin sheet testers, open resonators, circular cavities, harmonic stripline cavities and Courtney resonators. The software controls common vector network analyzers made by Agilent, Anritsu, and Rohde and Schwarz. The programs are automated, and lead the user through all steps required to perform measurement and calibration. In most instances the measurements require no direct user interaction with the network analyzer.

The VeloceRF™ v1.5 features an enhanced Spiral Wizard™ inductor synthesizer, several improvements in its rapid RLCK modeling engine and new features addressing Design for Manufacturability for 90 nm and 65 nm RFICs. The synthesis engine now supports the creation of patterned shields that enhance inductor Q-factor and improve substrate isolation. Version 1.5 efficiently addresses DFM requirements emerging for RF CMOS at the 90 nm process node and below. Features such as conductor track slotting to mitigate metal stress, geometry resizing under current density constraints and the use of dummy fill patterns are now programmed into the VeloceRF inductor library and are consistently supported by the Spiral Wizard, the modeling engine, and the layout and LVS modules.

Parametric Product Search Tool

The parametric product search tool is designed for the RF engineer to specify important product parameters and view the company’s products that match a specific requirement in a specification-compliance format. Unlike conventional search engines that eliminate products that narrowly fall outside of specification, the parametric product search tool can show these products allowing the engineer to make intelligent design trade-off decisions to “fine tune” the requirement to specific needs. View this and other product software support tools including Product Cross Reference, PLL Phase Noise and Mixer Spur Chart Calculators on the company’s site.

The company announced a number of new products and enhancements to its electromagnetic analysis software, XSTREAM, the hardware acceleration package for XFDTD, a full-wave 3-D electromagnetic (EM) solver. It provides much faster calculation speeds than using a CPU alone. A parallel/multiprocessing version of Wireless InSite v2.3 is now available. This multiprocessor and cluster-based version enhances the well-established propagation prediction tool. VariPose v1.2 is also now available. It provides for repositioning of the Male Visible Human mesh including internal anatomical structures. One new feature is that VariPose now has an enhanced skeleton head, allowing precise positioning of hands and cell phone near the head.
